IMPROVEMENT IN THE MANUFACTURE OF SPRlG-WORK FOR JEWELRY.

Specification forming part of Letters Patent No. 212,848, dated March 4,1879 application filed December 11, 1878. i

To all whom it may concern:

Be it known that I, LOUIS HEOKMANN, of VVrentham, in the county ofNorfolk and State of Massachusetts, have invented a new and usefulImprovement in the Manufacture of Sprig-VVork for Jewelry, of which thefollowing is a specification:

The sprig-work for jewelry ornamentation now in the market consists ofsprigs of leaves, flowers, 850., struck up in dies and soldered to wirestems, so as to be used as jewelry trimming.

In my improvement, I strike up a base of sprig-work which may be exactlysimilar to that above described, or in which the struckup leaves, 8m,may be reversed, and I surmount the leaves and flowers with caps ofvarious sha-pessay a cap upon each petal, for instance, cut out of metaland soldered to the said base.

By this combination, a piece of sprig-work is produced which isextremely handsome and rich in appearance, has fine effects in light andshade, and when made in plate is very suggestive of solid gold work.

It will readily be understood that it is mechanically impossible toproduce the necessary shape of my sprig-work by means of dies.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figure 1 is a view of a piece of sprig-workembodying my improvement. Fig. 2 is a side view of a detached sprig,showin the struckup base and the cut-out caps. Fig. 3 is a side view ofa detached flower, with the caps soldered to a reversed base, and alsoof the caps removed. Fig. 4. is a plan view of the same separated. Fig.5 is a section of the same joined. Fig. 6 is a section of the same withthe base or struck-up portion not reversed.

Fig. 7 is a view of a leaf made in the old wayi. 6., struck up, andwithout caps.

to a represent the struckup base portions of the sprigs, both leaves andflowers. These portions are attached to the wire stem in the ordinaryway. I) b are the caps, soldered to the base-leaves a and the petals ofthe baseflowers a. The caps may be of any desired shape or size, and maybe petals or entire flowers, always being used, however, as capssoldered to bases. In Figs. 2 and 6 they are soldered to bases in theirnatural positions, and in Figs. 3 and 5 to reversed bases.

The eifect produced by this arrangement is very fine, and entirelyunknown, previous to this improvement, in sprig-work trimming.

I do not wish to confine myself to struckup bases, as there may be someother practicable method of formin them.

Having thus fully described my improve ment, what I claim, and desire tosecure by Letters Patent, is

1. The hereinbefore-described improvement in the manufacture ofsprig-work for jewelry, consisting in surmounting the struck-up orotherwise formed leaves, flowers, petals, &c., with caps of variousshapes cut out of metal, and soldered or otherwise applied thereto, asand for the purpose described.

2. The hereinbefore-described sprig-work for jewelry, consisting ofbases struck up or otherwise formed, surmounted by caps cut out ofmetal, the whole being soldered or otherwise attached to a stem, allsubstantially as set forth, as an improved article of manufacture.
